Calories = MET × Weight(kg) × Time(hours); Outdoor adds ~8% for wind resistance and terrain
A 150 lb person running 30 minutes burns ~330 cal indoors vs ~356 cal outdoors (8% more).

Do I burn more calories exercising indoors or outdoors?

Outdoor exercise typically burns 5-10% more calories due to factors like wind resistance, varied terrain, and temperature regulation. Running outdoors requires more energy than treadmill running at the same speed because you're propelling yourself forward rather than being moved by the belt.

Why does outdoor exercise burn more calories?

Outdoor activities involve natural variations in terrain, wind resistance, and the need for balance and stabilization. Your body also works harder to regulate temperature in outdoor conditions, especially in cold or hot weather.

Is one better for weight loss?

Both can be effective for weight loss. Outdoor exercise may burn slightly more calories, but indoor exercise offers consistency regardless of weather. The best choice is the one you'll do consistently. Many people benefit from combining both approaches.

How does weather affect calorie burn?

Exercise in cold weather can increase calorie burn as your body works to maintain core temperature. Hot weather also increases energy expenditure due to cooling mechanisms like sweating. However, extreme conditions can limit performance and duration, potentially reducing total calories burned.
